Can you elaborate on what you mean with "Scaler method"? If your input/conversion API doesn't support any YUV420sp conversion modes (try to search for NV12 or NV21), you could use a Renderscript based or NEON optimized software conversion instead. See here, for example: https://code.google.com/p/libyuv/ Or, if you have fast RGB->YUV420p conversion in place, you could do the UV plane interleaving by hand. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
